Answer: Option B.
Step-by-step explanation:
The shapes of the conduction patterns may be associated with geometrical forms, which may be very useful to learn them in a first approach.
the measure 2/4 looks like a small pipe or an inverted "J" letter.
The measure 3/4 looks like a 2/4 but more triangular, so this is the one that looks like a triangle.
The measure 4/4 looks like the 3/4, with a small loop in the bottom right,
the measure 4/8 looks like 4/4 but the loop is bigger and has more "jumps" that indicate each of the beats.
